Making HCR LVT fonts
====================

Scripts and feature files for making HCR LVT fonts

Hamchorom (HCR) fonts are Korean fonts bundled in Hangul Word Processor
(HWP) program, and the fonts are freely downloadable at
https://www.hancom.com/support/downloadCenter/download
(direct link: https://cdn.hancom.com/pds/docs/HancomFont.zip).
These scripts target HCR fonts version 2.120 (build 20170407).

The fonts contain Old Hangul glyphs for conjoining jamo characters,
but their OpenType support outside HWP is incomplete: no vertical
writing tables and no ccmp-based Old Hangul shaping, so applications
other than HWP give quite unpleasant results.

The purpose of this project is to add GSUB and GPOS tables to HCR fonts
for processing Old Hangul documents. Additionally, vhea and vmtx tables
will be added to support vertical writing mode. Again, 'LVT' will be
added to the family name of these fonts, so as to be distinguished from
original HCR fonts.
